UniPower Radial Installation and Maintenance Manual - Mod.D
Maximum working load
WARNING!
The maximum working load (MWL) for the UniPower Radial Winch is 900 Kg (1984 lb).
Subjecting the winch to loads above the maximum working load can cause the winch to fail or
pull off the deck suddenly and unexpectedly during high loads causing severe injury or death.
Outline
Installation
The winch must be installed on a at area of the deck, reinforced if necessary to bear a load equal
to at least twice the maximum working load of the winch. It is the installer's responsibility to carry
out all structural tests needed to ensure that the deck can bear the load. Harken®does not supply
the screws needed to install the winch since these may vary depending on the deck on which it
is to be installed. It is the installer's responsibility to choose the correct screws taking account of
the loads they will have to bear. Harken®assumes no responsibility for incorrect installation of its
winches or for an incorrect choice of mounting screws.
DANGER!
Incorrect installation of the winch may cause severe injury or
death. Consult the yard that built the boat in the case of doubt
over the correct positioning of the winch.
WARNING!
Failure to use the correct number and type of mounting fasteners
or failure to ensure the correct deck strength can result in the
winch pulling off the deck suddenly and unexpectedly during
high loads causing severe injury or death.
WARNING!
Verify the entry angle of the sheet.This must be 8° with tolerance
of ±2°, to avoid sheet overrides and damaging the winch or
making the winch inoperable leading to loss of control of the boat
which can lead to severe injury or death.

Once you have decided the correct mounting position for the winch on the deck and checked the
space available below deck for the motor and electrical wiring, proceed with the installation.
Installation procedure
To install the winch, remove the drum and use Socket Head (SH) bolts.
Tools needed
One medium at-bladed screwdriver
To identify the various parts, refer to the exploded view at the end of this Manual.
Torque to apply when assembling
Install the winch on the deck in the position you have chosen, keeping in mind the limits described
on page 4 and using socket head (SH) bolts.
Carry out Installation procedure, then install the winch on the deck in the chosen position.
1. Unscrew the central screw ( 2Nm/18 in-lb)
3.Unscrew the three screws n°25 (4Nm/35 in-lb)
and remove the self-tailing arm n°8 by
rotating and lifting it.
2.Slide off the assy socketn°31 and the cover n°13
4. Lift off the drum n°27

NOTICE
Before drilling the deck, check the space available below deck for the motor.
A. Locate the point where you have decided to place the winch.Drill the deck with a Ø140 mm
hole, insert the motor through the hole, position the base of the winch on the deck and mark
the position of the holes.
Winch can be mounted in any direction without concern for drive gear location.
Below is a reduced scale diagram.
The drilling cut out template is available on the Harken®website, www.harken.com
B. Remove the winch and drill the ve 8.5 mm diameter holes and the 140 mm hole.
C. Bolt the base of the winch to the deck using ve socket headed M8 (not supplied by Harken®),
correctly chosen for the thickness and type of the boat deck. Consult the yard that built the boat in
case of doubt.
WARNING!
To install the winch on the deck, use only bolts in A4 stainless steel (DIN 267 part11).
Bolts made of other materials may not have sufficient strength or may corrode which can
result in winch pulling off deck suddenly and unexpectedly during high loads causing severe
injury or death.
NOTICE
To mount winches on the deck, do not use countersunk bolts.
D. Fill the mounting holes with a suitable marine sealant.
E. Remove the excess adhesive/sealant from the holes and base drainage channels.
F. Reassemble the winch following the steps in Installation procedure in the reverse order, and
apply the products indicated in the section on maintenance.
NOTICE
Before closing the winch, makesure the holes and drainage channels in the base of the winch arenot obstructed.
Positioning the self-tailing arm
Position the self-tailing arm so that the line leaving the winch is led into the cockpit.

Electric equipment
To guarantee greater efficiency in terms of safety and long life, for every winch model is mandatory
to install the Dual Function Control Box.
To fasten the Dual Function Control Box containing solenoids to bulkhead or wall, for all
installation details and for all electric wiring schemes, refer to the Dual Function Control Box
manual.
WARNING!
Before installing and using the device, read carefully the Dual Function Control Box manual
available on web site www.harken.com

NOTICE
To connect motor, attach cable terminals to clamps between
nut and lock nut. Hold nut in contact with motor using
a spanner and tighten other nut with second spanner.
Take special care not to turn the central spindles. These
instructions apply when assembling and disassembling. We
recommend using a torque wrench so as to obtain a torque
equal to and no greater than 10 Nm (88 in-lb).
NOTICE
Note that correct electrical contact sequence is:
Nut – Cable Terminal – Self-Locking Washer – Lock Nut

Maintenance
Washing
Winches must be washed frequently with fresh water, and in any case after each use.
Do not allow teak cleaning products or other cleaners containing caustic solutions to come into
contact with winches and especially anodised, chrome plated or plastic parts.
Do not use solvents, polishes or abrasive pastes on the logos or stickers on the winches.
Make sure that the holes and drainage channels in the base of the winch are not obstructed so
that water does not collect.
Maintenance table
Winches must be visually inspected at the beginning and end of every season of sailing or racing.
In addition they must be completely overhauled, cleaned and lubricated at least every 12 months.
After an inspection, replace worn or damaged components. Do not replace or modify any part of
the winch with a part that is not original.
WARNING!
Periodic maintenance must be carried out regularly. Lack of adequate maintenance
shortens the life of the winch, can cause serious injury and also invalidate the winch
warranty. Installation and maintenance of winches must be carried out exclusively by
specialized personnel.
In the case of doubt contact Harken®Tech Service at [e-mail]
WARNING!
Make sure that the power is switched off before installing or carrying out maintenance on
the winch.
